The Party Superstore was/is my absolute favourite London shop until it was bizarrely attacked and gutted during the summer London riots. They have been since adopted as a concession by the local Debenhams but you can still savour the full delights of the products and nonsense on line.

Favourite walk at night, especially in the summer.  Quite dramatic, very romantic. 

The many book stores dotted along this strip can provide hours of inspiration. Aside from those selling new books, several specialise in second-hand and antiquarian books.

Great little cinema, hidden away in the basement of Aubin & Wills, London. Not exactly a fan of the brand but the cinema is pretty awesome. They show a variety of interesting films and have probably the comfiest seats including armchairs and sofas. Bit dear, but one of the best cinemas I've come across.

They mainly sell art and cultural theory books but they also have a good selection of small press and self-published zines. It’s a great place to browse and get ideas.
